For the home appliance industry, security has always been a concern problem. Due to misoperations, electrical wiring systems may have current overload or short circuit problem and caused burning of plastic materials. Therefore, various fire protection requirements have been developed to evaluate and determine the flammability level of materials used in electrical appliances. The glow wire test is one of the relevant fire prevention requirements adopted by the household appliance industry nowday.

As we all know, there have been various methods for assessing the flammability and fire resistance of materials. It is including direct and indirect flame combustion test methods. The standard UL94 is an example of a direct flame combustion test method. This method, which has been used for a long time, is to apply a flame directly to a vertically or horizontally mounted sample under controlled conditions. Conversely,the indirect flame combustion method is to apply a heat source to the sample. The glow wire test is an example of an indirect flame combustion method. The test results obtained from using these methods can be used to compare the flame retardant, auto-extinguish (if lightering) of the material and the possibility that the drip formed by the combustion does not cause flame spread.

Drip Irrigation is a more economical and conservative way to irrigate just about anything. Most irrigation systems work on the basis of saturation. This means that you saturate a large area for short periods of time. The soil gets wet, which takes water down to the roots. However, the soil in between, in front of, and behind the plants also becomes saturated. This doesn't help provide more water to the roots. It just makes the dirt wet.

When you use drip irrigation you provide a steady but slow supply of water directly to the plants or even directly to the root systems. By using a continuous but slow drip the roots are always receiving the water that they need while keeping water use to a minimum. When you use this method you are providing a greater amount of water directly to the roots while you are using less than half of the water needed to operate a traditional irrigation system.

There have been many versions of drip irrigation over the centuries. This was a method that was initially derived from clay pots that were placed in the ground next to the root system. The pots were filled with water and the clay acted as a sponge, soaking the water from the inside of the pot and then allowing the soil next to the roots to absorb it.
